Hi drs-nyc and elliot upon facing this problem I did come up some solution. Some one in the forum did suggest to use post.
Here’s the code:
function is_field_group_exists($value, $type='post_title') {
$exists = false;
if ($field_groups = get_posts(array('post_type'=>'acf-field-group'))) {
foreach ($field_groups as $field_group) {
if ($field_group->$type == $value) {
$exists = true;
}
}
}
return $exists;
}
